NWS Jackson, MS wrote its last area forecast discussion before the first event at Jul 16, 2:34 PM CST, 2 hours 56 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 334 PM CDT SAT JUL 16 2011 .SHORT TERM...THE RISK OF STRONG CONVECTION WILL BE DIMINISHED IN THE SHORT TERM. THE COMBINATION OF INCREASING HEIGHTS/WARMER UPPER LEVEL TEMPS AND COOLER LOWER LEVEL CONDITIONS WILL RESULT IN WEAKER LAPSE RATES AND VERTICAL TOTALS FIELDS IN THE LOWER 20S. DEEP MOISTURE WILL REMAIN IN PLACE HOWEVER AND PRECIPITABLE WATER VALUES WILL GENERALLY RANGE ABOVE 2 INCHES AGAIN FOR SUNDAY. A WEAK SURFACE BOUNDARY WILL EXTEND ALONG OR JUST S OF OUR SRN ZONES TO PROVIDE WEAK FORCING WITH ADDITIONAL SUPPORT LENDED BY AN UPPER TROUGH THAT WILL TRACK WWD ALONG THE GULF COAST. WEAK FORCING OVER THE AREA WILL RESULT IN SCATTERED CONVECTION...THE BETTER RAIN CHANCES OCCURRING S OF I-20 WITH THE BEST POPS PAINTED ALONG AND S OF HWY 84. WITH LITTLE IN THE WAY OF CAPE...OTHER THAN SRN/SWRN ZONES... AND LIMITED LAPSE RATES THUNDERSTORM ACTIVITY SHOULD REMAIN OF THE ISOLATED VARIETY WITH MOST PRECIP COVERAGE IN THE FORM OF AFTERNOON SHOWERS. MODELS INDICATE THAT THE SURFACE BOUNDARY WILL REMAIN PARKED IN THE VICINITY OF THE SRN FORECAST BORDER MONDAY WITH A SLIGHT NRN SHIFT POSSIBLE AS THE SURFACE TROUGH BROADENS SLIGHTLY. THIS WILL MAINTAIN THE BEST RAIN CHANCES OVER SRN ZONES FOR MONDAY WITH DECREASING POPS FOR NRN ZONES WHERE FORCING DECREASES AND SLIGHTLY DRIER AIR SEEPS INTO THE REGION FROM THE NE. PRECIPITABLE WATER VALUES WILL ALSO DECREASE SLIGHTLY FROM THE N BY MONDAY AFTERNOON. WITH DEEP MOISTURE AND ASSOCIATED CLOUD COVER IN PLACE... TEMPERATURES WILL REMAIN CLOSE TO SEASONAL NORMS INTO EARLY NEXT WEEK. SLIGHTLY DRIER DEWPOINTS WILL BE WORKING IN FROM THE NE TO TAKE AN ADDITIONAL EDGE OFF AFTERNOON HEAT INDEX VALUES AT SOME LOCATIONS. .LONG TERM...TUESDAY THROUGH NEXT SATURDAY...FOR THE UPCOMING MED RANGE/LONG TERM THE GENERAL PATTERN WILL BE FOR A STOUT UPPER LEVEL RIDGE SITUATED TO OUR NORTH. THIS WILL OFFER BELOW AVG TO AVG PRECIP POTENTIAL WITH A GENERAL WARMING TREND BY MID WEEK AND INTO THE LATER PORTION OF NEXT WEEK. FOR TUE...A PORTION OF THE AREA WILL STILL BE UNDER THE INFLUENCE OF DEEPER MOISTURE AND HAVE SOME REFLECTION OF THE SFC PRESSURE TROUGH LINGERING. THIS AREA WILL BE ACROSS THE S/SW HALF AND BE THE LOCATION WITH THE BETTER PRECIP POTENTIAL. MOVING IN FROM THE EAST WILL BE AN OVERALL DRIER AIRMASS WHICH SHOULD PUT A HALT TO PRECIP CHANCES FROM EAST TO WEST FROM MON AFTERNOON INTO MON EVE. PW'S WILL DROP FROM 2.2 IN TO 1.5-1.6 DURING THIS TIME WITH THE LOWEST VALUES (DRIEST AIR) OVER THE AREA ON TUE. AT THIS TIME TUE LOOKS TO BE A DAY WITH LITTLE TO NO PRECIP POTENTIAL. FOR WED-SAT...INCREASING ATMS MOISTURE WILL MOVE IN FROM THE NE/E AS A POCKET OF MOISTURE ROTATES INTO THE REGION AROUND THE UPPER RIDGE. WHILE THE OVERALL MOISTURE WILL BE INCREASING...THE UPPER RIDGE WILL STILL HAVE SOME INFLUENCE AND PRECIP POTENTIAL WILL NOT INCREASE THAT MUCH. AT THIS POINT...GFS GUID IS OFFERING 20-30% TYPE CHANCES AND AT THIS POINT...CANNOT ARGUE AGAINST THAT WHICH IS RIGHT AROUND AVG FOR THIS TIME OF YEAR. AS FOR TEMPS...SOME SMALL ADJ WERE MADE TO THE MOST RECENT GUID. BY TUE...LOOK FOR TEMPS TO WARM A BIT...BUT LIKELY NOT TOO QUICKLY AS GROUND MOISTURE WILL HOLD TEMPS IN CHECK A BIT. FOR MID TO LATE WEEK...LOW LEVEL TEMPS ARE PROGGED TO INCREASE AND BE MORE SUPPORTIVE OF TEMPS RANGING FROM 95-98. /CME/ && .AVIATION...ISOLD-SCT SHWRS AND ISOLD TSRA WILL LIKELY AFFECT THE ENTIRE ARKLAMISS THIS AFTN INTO THE EVENING...ALTHOUGH THE BEST CHANCES REMAIN SOUTH OF I-20. SEVERE WEATHER IS NOT A CONCERN TODAY... HOWEVER PILOTS SHOULD BE AWARE OF WIND SHEAR/TURB INVOF ANY SHWRS/STORMS...OTHERWISE SFC WINDS WILL BE LGT AND ERLY THRU THE DAY. A RETURN OF MVFR/IFR CIG FOR AREAS ALONG AND SOUTH OF THE NATCHEZ TRACE PKWY SEEMS REASONABLE ONCE AGAIN TOMORROW MORNING 09-14Z. IN ADDITION...A FEW SHWRS MAY PERSIST THRU TONIGHT INVOF HBG/PIB (POSSIBLY MEI) AS A DISTURBANCE SHIFTS WEST ALONG THE GULF COAST. /BK/ && .PRELIMINARY POINT TEMPS/POPS...
